XT27G01ATSIGA 产品概述

一、产品简介

XT27G01ATSIGA(XT27G01A)是芯天下(XTX)推出的一款单通道 3.3V、1Gbit NAND 可电擦可编程只读存储器(NAND E2PROM)。器件组织为 (2048 + 128) 字节 × 64 页 × 1024 块,提供高密度存储与块级擦除管理,适用于嵌入式存储、数据记录与代码存储等应用场景。封装为 TSOP48(12×20×1.2 mm),易于在主流 PCB 设计中替换与布局。

二、主要功能特性

  • 硬件写保护功能,增强数据保护能力;
  • 读缓存(Read Cache)机制,提高顺序读性能;
  • 内置 ECC 纠错功能,提升数据可靠性;
  • 软件复位(Software Reset)支持系统级错误恢复;
  • 复制回写(Copy-back)功能,便于块内数据移动与管理。

三、存储组织与数据通路

器件的页面长度为 2176 字节(2048 字节有效数据 + 128 字节 Spare),每块包含 64 页,因此每块大小为 2176 × 64 = 139,264 字节(即 128KB + 8KB Spare)。器件内部设有 2176 字节的静态寄存器(page buffer),允许以 2176 字节为增量在寄存器与存储单元阵列间传输数据,简化编程与读取流程。

四、关键性能指标

  • 存储容量:1 Gbit;
  • 时钟频率(fc):最大 40 MHz;
  • 工作电压:2.7 V ~ 3.6 V(典型 3.3 V);
  • 写周期时间(Tw):25 ns(CLE/ALE 等时序参考);
  • 页写入时间(Tpp):典型 300 μs;
  • 块擦除时间(tBE):典型 2.5 ms;
  • 数据保留(TDR):10 年;
  • 工作温度范围:-40 ℃ ~ +85 ℃;
  • 待机电流:典型 50 μA。

五、可靠性与适用场景

XT27G01ATSIGA 提供工业级温度范围与十年数据保留保证,适合工业控制、消费类存储扩展、车载信息娱乐(非关键安全子系统)、固态日志记录器等需要长期保存与频繁擦写的应用。内置 ECC 与写保护机制,提升数据完整性与系统可用性。

六、封装与兼容性

封装:TSOP48(12 × 20 × 1.2 mm),引脚定义与主流 NAND 接口兼容,便于在现有平台中替换或升级。具体信号时序与命令集请参考器件数据手册以完成电气与布局设计验证。

七、设计注意事项

  • 在系统上电/复位时需遵循推荐的上电顺序及软件复位流程;
  • 对于频繁写入场景,建议结合主控端的磨损均衡与坏块管理策略;
  • 使用内置 ECC 与读缓存以降低系统主控负担并提升读写性能;
  • 合理配置硬件写保护信号用于防止误写或固件被篡改。

XT27G01ATSIGA 以其高密度存储、成熟的 NAND 功能集合及工业级可靠性,适合对容量、寿命与数据完整性有较高要求的嵌入式存储应用。欲获取完整时序、引脚与命令详情,请参阅 XTX 官方数据手册。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
